Spin-resolved photoemission spectroscopy has been performed on thick magnetized ferromagnetic single crystal layers of MnAs(1101) and MnAs(1100) grown onto GaAs(001). We observed large spin polarization from Mn 3d states in the valence band of these materials and strong intensity enhancement in the majority-spin spectrum at the photon energy slightly above the Mn 3p core excitation threshold. Band positions are determined for MnAs(1101), which are consistent with the LAPW band-structure calculation. Exchange splittings at the L-point derived for two different bands from data measured at MnAs(1101) are 2.1 ± 0.3 and 2.7 ± 0.5 eV. They are slightly larger than the calculated values.
